I have the 20 f2.8 but hardly ever use it as I also have the 17-35 AFS. I found that there is unaceptable color finging, I sent it back to Nikon but they said there was no problem. This is cropped from the edge of a D1x shot, its very soft, partly due to it being out of focus, as it was not the main subject area, partly because of the lens.
